Description

[Technical field]

[0001] The utility model relates to a baby stroller. [Background technology]

[0002] The existing child stroller includes a foldable bottom support frame, a foldable strut assembly is provided on the bottom support frame, and a seat assembly that can rotate and change direction is also provided on the bottom support frame, the seat assembly includes a seat portion and a backrest portion that can be rotated relative to the seat portion to be unfolded or folded. When unfolding this child stroller, the strut assembly needs to be rotated upward, and the strut assembly can push the backrest portion to unfold upward when rotating. However, the existing locking device will lock the backrest portion at the maximum angle gear when the backrest portion is unfolded upward. When the backrest portion is locked at the maximum angle gear, the backrest portion and the seat portion are in a lying state. Due to the interference of the backrest portion, the strut assembly cannot continue to rotate upward to unfold. When operating, the user needs to unlock the locking device and push the backrest portion with one hand, and push the strut assembly with the other hand to complete the unfolding of the entire child stroller, which is more troublesome to operate.

[0003] The present invention is developed based on the above-mentioned shortcomings. [Contents of the utility model]

[0030] The utility model is further described below in conjunction with the accompanying drawings:

[0031] like Figures 1 to 15 As shown, the utility model provides a child stroller, including a foldable bottom support frame 2, to which a strut assembly 3 capable of rotating and folding relative to the bottom support frame 2 is connected, to which a seat assembly 1 capable of rotating and reversing relative to the bottom support frame 2 is connected, and the seat assembly 1 includes a seat portion 11 connected to the bottom support frame 2, to which a backrest portion 12 capable of rotating relative to the bottom support frame 2 and folding toward the strut assembly 3 when the child stroller is folded is connected, and a locking device 13 capable of locking the seat portion 11 and the backrest portion 12 at different angular positions is provided between the seat portion 11 and the backrest portion 12, and a stop assembly 14 capable of preventing the locking device 13 from locking the backrest portion 12 at a maximum angular position during the process of the backrest portion 12 rotating and unfolding relative to the bottom support frame 2.

[0032] When the stroller of the utility model needs to be unfolded, the backrest 12 is first pushed to rotate upward. When the backrest 12 is rotated to the maximum angle gear, the stop assembly 14 provided on the seat portion 11 can prevent the locking device 13 from locking the backrest 12 and the seat portion 11 at the maximum angle gear. When the backrest 12 is rotated to a gear less than the maximum angle gear, the locking device 13 is separated from the stop assembly 14, and the locking device 13 can lock the backrest 12 and the seat portion 11 at the angle gear. Then the support rod assembly 3 is rotated to move upward. Since the backrest 12 is not stopped at the maximum angle gear, the backrest 12 will not interfere with the rotation and unfolding of the support rod assembly 3, and the entire stroller is fully unfolded when the support rod assembly 3 is rotated to a preset position relative to the bottom support frame 2. Since the stop assembly 14 prevents the locking device 13 from locking the backrest portion 12 and the seat portion 11 at the maximum angle, the user does not need to operate the operating member on the locking device 13 to keep the locking device 13 unlocked when unfolding the child stroller. The user can avoid the backrest portion 12 from staying at the maximum angle by simply pushing the backrest portion 12 to rotate upward, thereby facilitating the unfolding of the support rod assembly 3.

[0033] When the backrest 12 and the seat portion 11 are locked at the maximum angle position, they are in a lying state. Therefore, when the backrest 12 is located on one side of the support rod assembly 3, the backrest 12 will resist the support rod assembly 3 when moving toward the maximum angle position. At this time, the support rod assembly 3 will interfere with the movement of the backrest 12. Therefore, the backrest 12 and the seat portion 11 can be locked at the maximum angle position only when the backrest 12 is away from one side of the support rod assembly 3.

[0034] like Fig.11 and Fig.13 As shown, the locking device 13 includes a locking position 131 arranged along the circumferential direction, and the locking device 13 also includes a locking member 132 that can be locked in or out of the locking position 131 when moving relative to the backrest portion 12. The backrest portion 12 is also slidably connected to an operating member 133 that is capable of pulling the locking member 132 out of the locking position 131. When it is necessary to adjust the angle between the backrest 12 and the seat 11, operate the operating member 133. After being operated, the operating member 133 pulls the locking member 132 to slide relative to the backrest 12. The locking member 132 disengages from the locking position 131 on the seat 11 when sliding relative to the backrest 12. At this time, the backrest 12 can be rotated relative to the seat 11 to adjust the angle between the two. When the backrest 12 is adjusted to the right position, the locking member 132 is again locked into the locking position 131 corresponding to the angle, and the backrest 12 is locked with the seat 11 again. At this time, the backrest 12 cannot be rotated relative to the seat 11.

[0035] like Fig.13As shown, the operating member 133 includes an operating block 1331 slidably connected to the backrest portion 12, a pull rope 1332 is connected between the operating block 1331 and the locking member 132, a first elastic reset member 134 capable of driving the locking member 132 to reset is also provided between the operating block 1331 and the backrest portion 12, and an elastic member 1333 capable of driving the operating block 1331 to reset is also provided between the operating block 1331 and the backrest portion 12. When the locking device 13 is unlocked, the operating block 1331 is operated upward. The operating block 1331 slides upward relative to the backrest portion 12 when operated. The operating block 1331 pulls the cable 1332 to move and compresses the elastic member 1333 during the upward sliding process. When the cable 1332 is pulled, the cable 1332 also pulls the locking member 132 to slide upward relative to the backrest portion 12. The locking member 132 disengages from the locking position 131 and compresses the first elastic return member 134 during the upward sliding process. At this time, the locking device 13 is completely unlocked, and the backrest portion 12 can be rotated relative to the seat portion 11 to fold or adjust the angle position.

[0036] like Fig.11As shown, the locking position 131 includes a minimum gear locking groove 1311 and a maximum gear locking groove 1312 which are arranged on the seat portion 11 along the circumferential direction, and an intermediate gear locking groove 1313 is also arranged between the minimum gear locking groove 1311 and the maximum gear locking groove 1312, and the stopper assembly 14 includes a shielding piece 141 which is rotatably connected to the seat portion 11 and can block the maximum gear locking groove 1312 or block the maximum gear locking groove 1312 and the intermediate gear locking groove 1313 at the same time, and the The shielding piece 141 is provided with a locking portion 1411 which can cooperate with the locking member 132 when the backrest portion 12 is unfolded relative to the seat portion 11, so that the backrest portion 12 drives the shielding piece 141 to rotate relative to the seat portion 11; the seat portion 11 is provided with a stop portion 142 which can prevent the shielding piece 141 from continuing to rotate when the shielding piece 141 is rotated to a preset position; and a second elastic reset member 143 is also provided between the seat portion 11 and the shielding piece 141, which can drive the shielding piece 141 to return to its original position after disengaging from the locking member 132. When the entire child stroller is in the folded state, the backrest 12 is located below the seat portion 11 and close to the support rod assembly 3. At this time, the snap-in portion 1411 on the shielding piece 141 is in abutment with the locking piece 132 on the backrest 12. When the backrest 12 is rotated to unfold upward, the locking piece 132 on the backrest 12 cooperates with the snap-in portion 1411 to drive the shielding piece 141 to rotate relative to the seat portion 11, and the shielding piece 141 gradually blocks the maximum gear locking groove 1312 during the rotation relative to the seat portion 11. Due to the obstruction of the shielding piece 141, the locking piece 132 cannot be inserted into the maximum gear locking groove 1312. Therefore, the backrest 12 and the seat portion 11 cannot be locked in the maximum angle gear, and the backrest 12 will not affect the support rod assembly 3. When the backrest 12 continues to rotate and the shielding piece 141 rotates to the predetermined position, the shielding piece 141 cannot continue to rotate due to the support of the stopper 142, and the backrest 12 continues to rotate. At this time, the locking member 132 on the backrest 12 is disengaged from the shielding piece 141. When disengaging from the shielding piece 141, the locking member 132 is inserted into the middle gear locking groove 1313 or the minimum gear locking groove 1311, and the seat assembly 1 is unfolded. At this time, the backrest 12 and the seat part 11 are locked at a gear less than the maximum angle. Therefore, the support rod assembly 3 will not be interfered by the backrest 12 during the upward rotation process. When the support rod assembly 3 is unfolded to the preset position relative to the bottom support member 2, the entire child stroller is fully unfolded.

[0037] like Fig.12 As shown, the engaging portion 1411 is a engaging groove provided on the shielding sheet 141 and capable of engaging the lower end of the locking member 132. When the backrest portion 12 is folded toward the support rod assembly 3, the locking member 132 on the backrest portion 12 is engaged with the engaging groove.

[0038] like Fig.12 As shown, the second elastic reset member 143 is a torsion spring, one end of which is connected to the seat portion 11, and the other end is connected to the shielding piece 141. When the locking member 132 is disengaged from the locking portion 1411, the torsion spring drives the shielding piece 141 to rotate in the opposite direction relative to the seat portion 11 and reset.

[0039] like Figure 4 As shown, the backrest 12 is rotatably connected with an armrest frame 15, and a connecting member 16 is provided between the armrest frame 15 and the seat portion 11 to be rotatably connected with the two. The upper end of the connecting member 16 is mounted on the front end of the armrest frame 15, and the lower end of the connecting member 16 is mounted on the front end of the seat portion 11. The armrest frame 15, the seat portion 11, the backrest 12 and the connecting member 16 cooperate to form a bib, which is safer for children to sit on, and the armrest frame 15 and the connecting member 16 can also be folded when the backrest 12 and the seat portion 11 are folded, thereby reducing the occupied space.

[0040] like Figure 7 As shown, the armrest frame 15 is detachably connected to the backrest portion 12 .
